I have a WPF application..In which I have an Image control in Xaml file. On right click of this image I have a context menu. I would like to have same to be displayed on "Left click" also. How do I do this in MVVM way ? Here is a XAML only solution. Just add this style to your button. This will cause the context menu to open on both left and right click. Enjoy! <Button Content="Open Context Menu"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <EventTrigger RoutedEvent="Click"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <BooleanAnimationUsingKeyFrames
